Where is mechanical turbulence typically found?

Mechanical turbulence is primarily found downwind of mountains or tall structures due to the disruption of smooth airflow caused by these obstructions. When wind encounters an obstacle like a mountain or building, it flows over and around these structures, creating turbulent eddies and currents in the air. This can result in significant turbulence in the wake of the obstacle, which can be particularly pronounced when there are strong winds.

other scenarios presented do not primarily focus on how obstacles interact with airflow. In stable air above sea level, airflow remains relatively smooth without significant disruption. Near bodies of water during the day, thermal turbulence is more common due to heating that creates convection currents, rather than mechanical turbulence from obstructions. While turbulence can occur inside clouds, it is generally associated with different atmospheric conditions, such as convection, rather than mechanical disruptions from surface features. Therefore, the presence of physical structures significantly influences the behavior of air, leading to mechanical turbulence predominantly in the described conditions.
